摘要：

The use of cartridge valves with high pressure and large flow rates in a hydraulic system usually causes serious vibration and noise issues. In this paper, a type of cartridge valve with silencing grooves was presented and its mathematic model was built up. Four types of silencing grooves were selected for the cartridge valve, and they were optimized separately based on the actual application system for testing the safety valve in hydraulic support. Through simulation, their silencing effects were analyzed. The U-shaped groove has been found to be dominant among all the investigated groove types and it can significantly reduce the peak pressure gradient of the tested valve compared with no grooves. This research not only provides a new solution for reducing the vibration and noise of a hydraulic system, but also presents an effective method for the design of silencing grooves on a cartridge valve.
